Why this result

Kimi K2.6 is clearly ahead on the provisional aggregate, 74 to 59. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Kimi K2.6's sharpest advantage is in agentic, where it averages 73.5 against 52. The single biggest benchmark swing on the page is Terminal-Bench 2.0, 66.7% to 41.6%. Qwen3.5-27B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.

Kimi K2.6 is also the more expensive model on tokens at $0.95 input / $4.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3.5-27B. That is roughly Infinityx on output cost alone. Qwen3.5-27B gives you the larger context window at 262K, compared with 256K for Kimi K2.6.
